Greencube batteries is a technology innovation built to increase performance with sustaining a longer battery life. With an aim to make Greencube batteries 100% coulometric efficient, our batteries contain salt i.e. Sodium Chloride (NaCl) & Nickel (Ni), which make them quicker, better and easy to maintain. Simply speaking, they are the future of battery technology.

A Greencube battery is made up of multiple cells that are connected in a series and placed parallelly against each other. When connected to an outer source of power the salt and nickel react to form Nickel Chloride (NiCl2) at the cathode and Sodium (Na) at the anode. The discharge of power occurs by the means of an opposite reaction with the sodium again reacting with Nickel Chloride at the positive electrode. Each cell is placed in metal containers that separates electrodes by ceramic barriers this allows sodium ions to pass through. Hence, the chemical reaction takes place only if the battery is supplied with power through an external circuit, ensuring no parallel reactions take place. The external cover of the battery is made up of a metal-ceramic material that seals and protects the internal unit of the battery. The open circuit voltage (OCV) per cell is 2.58V which remains constant for most of the discharge profile.

This gives Greencube batteries an edge over conventional batteries, making it a lifelong maintenance-free investment.

  • Extremely low running cost
  • Guarantees high performance in any temperature
  • High power storage capacity
  • Light and durable (weighs 40% less than lead batteries)
  • Zero emissions
  • Quick charging and discharge facility
  • Non-toxic material
  • 100% safe
  • No maintenance
  • Recyclable
  • Guarantees safety
  • Flexible installation (Kwh-Mwh)
Greencube battery is an innovation designed to give you maximum performance at negligible degradation. The high durability and compact sizing, which is almost 30% smaller than conventional batteries available in the market, make Greencube batteries a safe, recyclable and maintenance-free investment.

The battery measures an internal temperature of 270° which assures high performance regardless of any external conditions or temperatures. The chemical composition and metal - ceramic coating makes Greencube batteries the preferred choice in the market.
